I

A spirally coiled spring 8 encircles the rod 6, forming a loose sleeve therefor, one end of the spring being secured to the rod between a pair of nuts 9 shown at the innermost end of the rod., The other end of. the spring is fixed to. the housing, adjacent the lower'end' of the latter, as by looping said end of the spring about a bolt 10 positioned diagonally through the adjoining sides of the housing. Obviously, the rod may be moved longitudinally of the housing, inwardly or out-Wardly, and without danger of the parts becoming displaced or lost.

The work-engaging element 5 may be of a suitable length of board, having securement' to the housing in some suitable manner, preferably so th'ata certain amount of longitu- 539 dinal adjustment therebetween may be'had,

as for example by providing a-series of apertures 11 through the part 5, through which a pair of bolts-12may be passed from within the housing, wing-nuts. 13 maintaining the parts in their adjusted relationship.

The device just described is extremely sturdy, econom cal, easy to set'up'jand take down, occupying but little space in'storage or I in place, and will remain in its desired posi- 1 39 tion as longas necessary, without paying further attention thereto after it is once set up, the spring automatically takingu'p any vibration of the scafloldthat may occur. There is no danger of the scafl'old-engaging rod slipas ping out of place, as itis rather small in diameter, sayabout' an inch or so, and will there fore'bit'e into the scaifold" itself and thereby :eep'i'ts engagement therewith.

Any number of these supports may be used 40, in case the single one is not sufficient, the devices being placed at suitable points so that they engage the work ata plurality of-points.

Having thus described my invention, it is obvious that various immaterial "modificae if; tions maybe had in the same Without depart ing-from the spirit of my invention; hence I do not wish to be understood as limiting myself to the-eXact-form, construction, arrangement and combinationofpartsherein shown 5e and described, or uses mentioned, except as limited by'the claim.

What I claim as new and desire to secureby Letters Patent is:

A work-holding support of the kind dec-J scribed, adapted to support a piece of Work overhead and comprising-a housing member, a scaztiold-engaging member: telescoping with said housing member, a coil spring encircling and receiving saidscaffold=engagingmember 6e therethrough'and. fixedatoneend'to the same and fixed. at its other end-to-the other member toresiliently control relative movement therebetween, substantially as described.
